Godforetold by the mouth of all the prophets that His Christ should suffer, He thus fulfilled. Repent therefore, and turn again, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord, and that he may send the Christ appointed for you, Jesus, whom heaven must receive until the time for establishing all that Godspoke by the mouth of his holy prophets from of old. Moses said, "The Lord God will raise up for you a prophet from your brethren as he raised me up. You shall listen to him in whatever he tells you. And it shall be that every soul that does not listen to that prophet shall be destroyed from the people." And all the prophets who have spoken, from Samuel and those who came afterwards, also proclaimed these days. You are the sons of the prophets and of the covenant which God gave to your fathers, saying to Abraham, "And in your posterity shall all the families of the earth be blessed." God, having raised up His servant-son, sent him to you first, to bless you in turning every one of you from your wickedness. Acts 3:18-26.

The gospel of God which He promised beforehand through Hisprophets in the Holy Scriptures concerning His son. Romans 1:3.

In many and various ways Godspoke of old to our fathers by the prophets but in these last days He has spoken to us in a Son, whom He appointed the heir of all things, through whom also He made the ages. He is the radiance of His glory and express image of His being, upholding the all things by his word of power. Having made purification for sins, he sat down at the right hand of the Majesty on high, having become as much superior to angels as the name he has obtained is more excellent than them. For to what angel did He ever say, "You are My son, today I have begotten you"? Or again, "I will be a Father to him, and he shall be to Me a son"? Hebrews 1:1-5.

The God of Abraham, Isaac, and Jacob, was Jesus' Father.

The God of Abraham, Isaac and Jacob, the God of our fathers, has glorified His servant-son* Jesus. Acts 3:13.

The God who promised to raise up the prophet Jesus was Jesus' Father

Moses said, "The Lord God will raise up for you a prophet from your brethren as he raised me up. You shall listen to him in whatever he tells you. And it shall be that every soul that does not listen to that prophet shall be destroyed from the people." And all the prophets who have spoken, from Samuel and those who came afterwards, also proclaimed these days. You are the sons of the prophets and of the covenant which God gave to your fathers, saying to Abraham, "And in your posterity shall all the families of the earth be blessed." God, having raised up His servant-son, sent him to you first, to bless you in turning every one of you from your wickedness. Acts 3:22-26 quoting Deuteronomy 18:15.

The Father who promised to raise up the prophet Jesus was the God whose voice they heard on Mt. Horeb (Sinai)

[Moses]: The LORD* your God will raise up for you a prophet like me from among you, from your countrymen, you shall listen to him. This is according to all that you asked of the LORD your God in Horeb on the day of the assembly, saying, 'Let me not hear again the voice of the LORD my God, let me not see this great fire anymore, or I will die.' The LORD said to me, 'They have spoken well. I will raise up a prophet from among their countrymen like you, and I will put My words in his mouth, and he shall speak to them all that I command him. It shall come about that whoever will not listen to My words which he shall speak in My name, I Myself will require it of him.' Deut 18:15-18; see John 3:34-35; 7:16; 8:28,38; 12:49; 14:10,24; 17:8,14.

The God who gave Israel Law is the Father whose voice they hear and who raised up the prophet Jesus.

Then God spoke all these words, saying, I am the LORD your God, who brought you out of the land of Egypt, out of the house of slavery. 3 "You shall have no other gods before Me. 4 "You shall not make for yourself an idol, or any likeness of what is in heaven above or on the earth beneath or in the water under the earth. 5 "You shall not worship them or serve them; for I, the LORD your God, am a jealous God, visiting the iniquity of the fathers on the children, on the third and the fourth generations of those who hate Me, 6 but showing lovingkindness to thousands, to those who love Me and keep My commandments. 7 "You shall not take the name of the LORD your God in vain, for the LORD will not leave him unpunished who takes His name in vain. 8 "Remember the sabbath day, to keep it holy. 9 "Six days you shall labor and do all your work, 10 but the seventh day is a sabbath of the LORD your God; in it you shall not do any work, you or your son or your daughter, your male or your female servant or your cattle or your sojourner who stays with you. 11 "For in six days the LORD made the heavens and the earth, the sea and all that is in them, and rested on the seventh day; therefore the LORD blessed the sabbath day and made it holy. 12 "Honor your father and your mother, that your days may be prolonged in the land which the LORD your God gives you. 13 "You shall not murder. 14 "You shall not commit adultery. 15 "You shall not steal. 16 "You shall not bear false witness against your neighbor. 17 "You shall not covet your neighbor's house; you shall not covet your neighbor's wife or his male servant or his female servant or his ox or his donkey or anything that belongs to your neighbor." 18 All the people perceived the thunder and the lightning flashes and the sound of the trumpet and the mountain smoking; and when the people saw it, they trembled and stood at a distance. 19 Then they said to Moses, "Speak to us yourself and we will listen; but let not God speak to us, or we will die." Exodus 20:1-19.
